SPECIFICATION forming part of Letters Patent No. 488,031, dated December13, 1892.

Application filed May 2, 1892. Serial No. 431,440- (No model.)

To all whom it may concern:

Be it known that we, JASPER N. SANDERS and DAVID C. HERRINGTON, of GrainValley, Jackson county, Missouri, have invented certain new and usefulImprovements in Cane- Mills, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part hereof.

Our invention relates to machines for expressing the saccharine juicefrom sugar-cane and also for similar and analogous purposes; and theobjects of our invention are to produce a cane-mill which shall besimple, strong, durable, and inexpensive in construction, and whichshall also be direct, positive, and very rapid and effective in itsoperation.

A further object of our invention is to produce a cane-mill which, inaddition to the advantages above enumerated, shall develop but littlefriction during its operation, and in which the pressure of thesqueezing-rolls shall be capable of ready control, so as to produce themost effective results.

To the above purposes our invention consists in certain peculiar andnovel features of construction and arrangement, as hereinafter describedand claimed.

In order that our invention may be fully understood, we will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 is a perspective view of a cane mill embodying our invention.Fig. 2 is a plan View of the same with the top gearing of the machineremoved. Fig. 3 is a horizontal section of the same on the line 3 3 ofFig. 1. Fig. 4 is a transverse vertical section of the same on the line4 4. of Fig. 3.

In said drawings, 1 designates the base of the machine, the said basebeing either of wood or metal, as preferred, and being also preferablyof approximately-heart shape, as shown, the base resting horizontallyeither upon a suitable horizontal support 2, having uprights 3, ordirectly. upon the ground, as preferred. Upon the upper side of the base1 is formed or suitably secured a flange 4:, which is preferably ofapproximately-trefoil shape, and the ends of which project parallel witheach other at the larger end of the base, so as to form a suitabledischarge-spout 5 for the expressed juices from the canes, the bottom 6,inclosed within the ridge 4, being preferably inclined downward towardthe spout 5, so as to facilitate the drainage of the juices from themachine. middle of the larger end of the base 1 are placed two verticalguards 7, each of which is of approximately-V form in cross-sections, asshown, and the concave sides of which are placed inward toward thesqueezing-rolls of the machine. At the opposite end of the machine isplaced a third vertical guard 8, which is also of approximately-V formin cross-section and which stands in line with the space between the twoguards 7, the concave side of this guard 8 being also presented inwardtoward the squeezing rolls of the machine.

At one side of the machineis placed a vertical ingress-guide 9 for thecanes, said guide being located near the edge of the correspond ingguard 7, and preferably having its two sides converging inwardly, asshown.

10 designates the top or cap piece of the machine, the said top or cappiece being either of Wood or of metal, aspreferred, and being alsopreferably of circular form in marginal contour, as shown. This top orcap piece 10 rests horizontally upon the upper ends of the guards 7 and8 and also uponthe upper end of the guide 9, and said top or .cap pieceis secured in its described position by a number-of vertical tie boltsor rods 11, which are passed downward through the top or cap piece, andalso similarly through the base 1, and to the lower ends of which aresecured suitable retaining-nuts, as indicated in dotted lines in Fig. 4,the lower ends of these rods or bolts 11 extending either through thesupport 2 or terminating at the under side of the base 1, as preferred.If the horizontal support 2 be used, the base 1 may be securely boltedto said support, as at 12; or if the supportbe not employed the machinemay be suitably anchored to the ground, so as to remain at all timesperfectly stationary and rigid. At its outer margin and on its upperside the top or cap piece is formed or otherwise provided with acircular flange 13, and at a slight distance from said marginal flangewith an inner circular and concentric flange 14, a circular At oppositesides of the guide-groove being thus formed between the flanges 13 and14, for a purpose to be hereinafter explained. At the margin of the topor cap piece 10 are formed three outwardlyextending lugs or cars 16,which are preferably so disposed that each is located opposite theinterval between the other two, and the purpose of these lugs or earswill be hereinafter explained.

17 designates the larger or main roll of the machine, and 18 its shaft,this roll being interposed vertically between the base 1 and the top orcap piece 10 and having the lower end of its shaft journaled in thebase 1. The upper end of the shaft 18 of the roll 17 projects upwardthrough the top or cap piece 10 of the machine, and the said roll islocated adjacent to the smaller end of the base 1 Upon the upper end ofthe roll-shaft 18 is mounted a horizontal gear-wheel 19, which liesabove the top piece 10.

20 designates the two auxiliary squeezingrolls of the machine, and 21the shafts of the same, the said auxiliary rolls extending parallel withthe main roll 17 and vertically between the base 1 and cap 10, at thelarger end of the base 1, and at points at opposite sides of the middleof the said larger end. The lower ends of the shafts 21 work withinelongated openings or slots 22, which are formed in the base 1 and whichconverge toward the opening 22, in which the lower end of the main-rollshaft 18 is inserted, while the upper ends of the shafts 21 extendthrough slots or elongated openings 23, which are formed in the cap 10and which converge toward the Opening 23, through which the upper end ofthe main-roll shaft 18 projects. Thus it will be seen that the auxiliaryrolls 20 are permitted to approach toward and to recede from the mainroll 17. These auxiliary rolls 20 are normally pressed into contact withthe main roll 17 by adjustable bearing-blocks 24:, which are mounted inguides 25, which latter are bolted or otherwise secured to the uppersides of the base 1 and cap 10. The blocks 24 are moved toward or awayfrom the main roll 17 by adjustingscrews 26, which pass through heads 27of the slides and the front ends of which abut against the rear ends ofthe guides, as shown. At its upper end each shaft 21 carries agearpinion 28, the teeth of which mesh with the teeth of the gear-wheel19 of the main roll 17, and it is to be observed that while theauxiliary rolls 20 are of equal diameter they are of much less diameterthan the main roll 17.

29 designates a gear ring or annulus, which is of slightly-less diameterthan the cap 10 and which on its under side is formed with an annulargroove 30, into which projects the guide-flange 14, the annular rib 31at the under side of the outer margin of the ring or annulus enteringthe groove 15 of the cap 10. Thus the ring or annulus is prevented fromlateral displacement from the cap 10 and said ring or annulus isprevented from vertical displacement by three retaining-1n gs 32,whichare bolted, as at 33, or otherwise secured to the upper sides of thelugs or cars 16 and which extend inward and upward,,so as to overlie theupper side of the ring 29, as shown. On its inner side the ring orannulus 29 is formed with a circular series of gear-teeth 34:, which areengaged by the teeth of the gearwheel 19 of the main-roll shaft 18.

Two arch-formed supports 35 are secured, as at 35, at their ends to theupper side of the ring or annulus 29 and extend parallel with each otheracross said ring, said arched supports being braced laterally by twosegmental braces 36, which are secured at their lower ends, as at 36, tothe upper side of the ring 29, and the upper ends of which are secured,as at 36 to the support 35. Midway of their length these arch-formedsupports 35 are formed with pendent U-shaped sockets 37, within which issecured, as at 38, a sweep or beam 39, to the ends of which the animalsfor operating the mill are suitably harnessed.

Now it will be seen that when the animals are started and caused totravel in a circular path the sweep is carried around with them, causingthe ring or annulus 29 to revolve and to transmit its motion, throughits gear-teeth 34, to the gear-wheel 19 of the main roll 17, andconsequently revolving said main roll. The motion of the main roll 17 iscommunicated through its gear-wheel 19 to the gearpinions 28 of theauxiliary rolls 20, and causing said rolls 20 also to revolve. The canesare inserted into the guide 9,and their entering ends are grasped by themain and auxiliary rolls of the machine, and said canes are squeezed soas to express the juice from the canes. This juice flows down the rollsand into the space within the flange at, and is guided thence throughthe spout 5 out of the machine.

From the above description it will be seen that we have produced acane-mill which is simple, strong, durable, and inexpensive inconstruction, direct and positive in its action, the operation of whichdevelops but little friction, and which effectively expresses the juices from the canes.

Having thus described our invention, what We claim as new therein, anddesire to secure by Letters Patent, is-

1. A cane-mill comprising a framework having a top or cap, a number ofparallel vertical rolls mounted in said framework, a circular grooveformed upon the top of the cap, and an internally-toothed gear-ringhaving a circular rib to engage said groove, substantially as set forth.

2. A cane-mill comprising a suitable framework having a top or capprovided with a circular groove and also with outwardly-projecting lugsor ears, an internally-toothed gear-ring mounted on said top or cap andhaving a circular rib to engage said groove, and a number ofretaining-pieces secured to the lugs or ears and overlying the ring,substantially as set forth.
